Summary:                    Terratec USB surround broken
Description: 
I'm using a Terratec USB 5.1 card. The 6 channels test correctly using
'./speaker-test -c6', but any attempt to use 5.1 channel in Xine, or using
'aplay -Dsurround51 file.wav' results in errors e.g.
-----
ALSA lib pcm.c:1851:(snd_pcm_open_conf) Invalid type for PCM surround51
definition (id: surround51, value: cards.pcm.surround51)
aplay: main:508: audio open error: Invalid argument
-----
Xine similarly fails saying the sound card is in use. Xine works fine for
stereo audio, even when configured to use 5.1 channel sound.

The contents of /proc/asound/card0/stream0 are:

Audio from, say, downloaded MP3s sounds fine, but any audio I've recorded
(in whatever program) has to have its sample rate changed, or it sounds
too fast.

I just tried 'default' in the configuration for 5.1 channel sound in Xine,
and it works just fine. Yay.

I forgot to mention, I'm recording through the digital (optical) input from
a 44.1kHz source (a MiniDisc deck).
